Increased temperatures in urban areas due to high energy consumption and greenhouse gas emissions are some of the problems of today's cities. Urban open spaces in hot and arid climates experience this problem more in summer. The purpose of this study is to show the relationship between morphological components of the urban fabric and thermal comfort through integrated analysis. In this study, urban fabric types were extracted by considering ground space index, floor space index, open space ratio, average height, streets orientation, streets organization, and type of plots according to their configuration of mass and space. To study thermal comfort, a field study was carried out in five neighborhoods in the historical context, for five continuous days in summer. Environmental variables including air temperature, humidity, radiant temperature, and wind speed were measured and the physiological equivalent temperature index was calculated using ENVI-met software and thermal comfort in the neighborhoods with different morphological characteristics was analyzed. The results showed that more than half of the data during the day in the hot season in all five neighborhoods are in conditions of extreme heat stress. Comparison of neighborhoods with different morphological features indicated that two neighborhoods with higher open space ratios, despite the difference in the orientation of the streets and the type of plots, have lower thermal comfort compared to other types. A neighborhood with a higher ground space index and a lower open space ratio has a lower average physiological equivalent temperature.

Since the most important climatic parameter affecting sugar beet cultivation is the temperature, we carried out this research considering climatic elements such as temperature, precipitation and freezing days in relation to autumn sugar beet planting. Daily temperatures of selected stations in a period of 10 years (2005-2015) has been used for agroclimatic analysis. In order to evaluate that, thermal potential assessment, deviation from optimal conditions and active day gradient index (GDD) were used. The evaluation of thermal potential based on the threshold of 0, 4, and 10 degrees Centigrade at the station levels in Kermanshah province showed that Sar-e-Pol-e-Zahab Station has the highest cumulative thermal unit and Kangavar Station has the least one. In Isfahan province, Khour-va-Biabanak station has the highest cumulative thermal unit and Khansar station has the lowest unit. Based on the deviation from optimal conditions in Kermanshah province, Sar-e-Pol-e-Zahab station has the lowest (-27.79) and in Khour-va-Biabanak station (-21.78) had the least deviation from optimal conditions. Planting date at the stations was considered based on the autumn temperature. In Kermanshah province, Sar-e-Pol-e Zahab station had the earliest date of harvest (May 1st.), while this date in Isfahan province was for Khour-va-Biabanak station (May 9th.). Suitable areas for planting in Kermanshah province are found to be the eastern and northeastern regions of Sar-e-Pol-e Zahab and Qasr-Shirin. In the province of Isfahan, the northern and western parts of Khour-va-Biabanak and Kashan were the most proper regions and central areas are in the next steps.
 

Isfahan City-Region is a collection of cities and towns with shareable common ground (such as communications, infrastructure, population and climate) at the geographical level of the city of Isfahan and its surroundings, and their social, economic, functional and spatial dependencies are such that one The geographically differentiated metamorphic and sub-regional divisions form the surface of the land and the main focus of its residential concentration is the city of Isfahan. These common features make it possible for them to complete complementary fields with single target targeting. Meanwhile, municipalities, as the main actor of urban management, play a major role in communicating cities and managing these relationships, so that these issues can play a common language among the actors in the city-region. This research is descriptive-analytic in terms of its main purpose. The analysis of locational problems and identification of key actors in Isfahan-Isfahan (including Isfahan and ten neighboring cities: Abrisham, Baharestan, Khomeinishahr, Khorzuq, Dorcheh, Dolatabad, Shahinshahr, Ghahjavarestan, Gaz, and Najafabad) is an applied research. For this purpose, in the first step, identifying problems between Isfahan and ten neighboring cities has led to the formulation of a statement of problems by using the dual paths of reviewing the documents of documents and urban plans and conducting interviews with city managers and experts. In the second step, analyzing the problems and problems of the cities located in the city-region of Isfahan, based on the six-tagged codes defined for each problem, the amount of weight (severity of the problem) is determined and, through the method of analyzing social networks, the network of "actors-problems" is drawn. Based on the findings of the analysis from this network, the problems of "Air pollution caused by the exhausted bus", "the occurrence of environmental problems caused by the destruction of the ecological capacity of West of Isfahan" and "shortage of fire fighting equipment in neighboring cities of Isfahan" are the most important of the city-region. The department of "Urbanism & Architecture", "Transportation" and "Urban Services" as acters paly the most key role in solving the problems of the city-region of Isfahan.

Agriculture, as one of the most important human economic activities, is closely related to the climatic conditions, and any changes in the climatic conditions can have dramatic changes in agriculture. The main objective of this study is to investigate the spatial changes of the Agro Climatic Feasibility Rosa damascena mill Cultivation in Climate change Condition in northern part of Isfahan province including Kashan, Natanz, Ardestan and Aran Bidgol, under the four carbon dioxide emission pathways (RCPs)of 2050.  Two groups of factors involved in agroclimatic feasibility of Rosa damascena mill cultivation including environmental factors (topography, soil) and climatic factors were extracted. Based on these factors, suitable zones of Rosa damascena mill cultivation, were identify using Fuzzy gamma function. In the next step, by simulating the climatic elements of the region in 2050, under the four carbon dioxide emission pathways, the fifth report of the IPCC, replacing the simulated climatic variables of 2050 under the four lines, by re-implementing the fuzzy gamma function, favorable areas of cultivation Rosa damascena mill was identified in each region in each scenario. In the next step, by simulating the climatic elements of the region in 2050, under the four carbon dioxide emission pathways, the fifth report of the IPCC, replacing the simulated climatic variables of 2050 under the four lines, by re-implementing the fuzzy gamma function, favorable areas of cultivation The Rosa damascena mill was identified in each region in each scenario. The results showed that in the base period climate, about 0.33% of the area (9025 km2) has a climate suitable for cultivating Rosa damascena mill and more than 67% of the area of ​​the region has a weak talent. The results of the simulation of the climatic conditions of 2050 under four carbon dioxide emission lines indicate that, under all scenarios, favorable areas for cultivating Rosa damascena mill in the studied area have increased. In the trajectory of 8/8 release, the highest class of agro-colliery was the cultivation of the flowers of Mohammadi gardens

 As it can take an efficient step towards the preservation and sustainability of such lands due to the preparation, implementation, and reformation of criteria. In District 9 of Isfahan Municipality, mismanagement in the preservation of ecological lands has destroyed gardens and agricultural lands, and has caused the loss of social unity of neighborhoods. Consequently, the study of ecotourism management in this region is of great significance. For this reason, in this paper, a model for ecotourism management with an emphasis on urban ecological textures is provided for District 9 of Isfahan Municipality. For this reason, first, the Star method has been used as a model for interviewing experts and relevant municipal experts in Isfahan city management. At that point, with the help of library investigations and field assessments, and implementation of the grounded theory method, 3 dimensions, 10 categories, and 35 subcategories are extracted from the data gained from the interview. The main dimensions are urban texture management (with categories legislation, planning, management of resources and control and supervision), the ecological texture (with the categories: protection and development and improvement), ecotourism (with the economic, social, environmental and cultural categories).
